To the guy asking about the yellow bulb to stock, she had the stock bulbs in there, but one of the fogs lense was busted up, so I went to parts.com and ordered a new one. When I got it the new fog u could see the actual bulb inside compared to the stock one(I think it has a bulb cover), so I ended up buying another new fog for the other side for it to match. Yellow compared to stock is a big difference at night, but the 5k HID is so much nicer then the stock. I had it done right by my body shop so the wires are drilled into the back of the headlamps and the ballast are mounted properly.
